n8n Workflow: Sync Open House Leads to HubSpot with Automated Email Follow-up

This n8n workflow is designed to automate the process of capturing open house leads (presumably from a platform like SignSnapHome, though the JSON doesn't explicitly state the source beyond a generic Webhook) and integrating them into HubSpot. It then intelligently triggers an automated email follow-up based on a specific condition.

What it does

This workflow streamlines lead management and follow-up by:

Receiving Lead Data: It starts by listening for incoming lead data via a webhook, which acts as the entry point for new open house leads.
Preparing Data: It uses a "Set" node to prepare and format the incoming lead data for subsequent actions. This likely involves mapping fields or adding default values.
Conditional Logic: It employs an "If" node to introduce conditional logic. This node checks a specific condition within the lead data to determine the next steps.
Creating/Updating HubSpot Contact: If the condition in the "If" node evaluates to true, the workflow proceeds to create or update a contact in HubSpot with the lead's information.
Sending Automated Email: Following the successful creation/update in HubSpot (and if the condition was met), an automated email is sent to the new lead.

Prerequisites/Requirements

To use this workflow, you will need:

n8n Instance: A running instance of n8n.
Webhook Source: A system or application (e.g., a lead capture form, an open house registration tool like SignSnapHome) configured to send lead data to the n8n Webhook URL.
HubSpot Account: An active HubSpot account with appropriate API access.
Email Sending Service: Configured SMTP credentials within n8n to send emails.

Setup/Usage

Import the Workflow:
- Download the provided JSON content.
- In your n8n instance, go to "Workflows" and click "New".
- Click the "Import" button (cloud icon) and paste the JSON content.
Configure Webhook:
- Open the "Webhook" node.
- Copy the "Webhook URL". This is the endpoint where your lead capture system should send data.
- Ensure the "HTTP Method" and "Response Mode" are configured correctly for your incoming data.
Configure HubSpot Credentials:
- Open the "HubSpot" node.
- Click on "Credential" and select or create a new HubSpot API credential. Follow the n8n documentation for connecting to HubSpot if needed.
- Map the incoming data fields to the appropriate HubSpot contact properties.
Configure "Edit Fields (Set)" Node:
- Adjust the "Edit Fields (Set)" node to transform or rename incoming data fields to match what HubSpot expects or what you need for your email.
Configure "If" Node:
- Open the "If" node and define the condition that determines whether the HubSpot contact is created/updated and the email is sent. For example, you might check if a specific field like interestLevel is set to "High".
Configure "Send Email" Node:
- Open the "Send Email" node.
- Select or create your SMTP email credentials.
- Configure the "To" address (e.g., {{ $json.email }} to use the lead's email).
- Write your subject and body for the automated follow-up email, using expressions to personalize it with lead data (e.g., Hello {{ $json.firstName }}).
Activate the Workflow:
- Once all configurations are complete, save the workflow and activate it by toggling the "Active" switch in the top right corner of the n8n editor.

Now, whenever new lead data is sent to the Webhook URL, this workflow will process it, integrate it with HubSpot, and potentially send an automated email based on your defined conditions.

Automated UGC video generator with Gemini images and SORA 2

This workflow automates the creation of user-generated-content-style product videos by combining Gemini's image generation with OpenAI's SORA 2 video generation. It accepts webhook requests with product descriptions, generates images and videos, stores them in Google Drive, and logs all outputs to Google Sheets for easy tracking. Main Use Cases Automate product video creation for e-commerce catalogs and social media. Generate UGC-style content at scale without manual design work. Create engaging video content from simple text prompts for marketing campaigns. Build a centralized library of product videos with automated tracking and storage. How it works The workflow operates as a webhook-triggered process, organized into these stages: Webhook Trigger & Input Accepts POST requests to the /create-ugc-video endpoint. Required payload includes: product prompt, video prompt, Gemini API key, and OpenAI API key. Image Generation (Gemini) Sends the product prompt to Google's Gemini 2.5 Flash Image model. Generates a product image based on the description provided. Data Extraction Code node extracts the base64 image data from Gemini's response. Preserves all prompts and API keys for subsequent steps. Video Generation (SORA 2) Sends the video prompt to OpenAI's SORA 2 API. Initiates video generation with specifications: 720x1280 resolution, 8 seconds duration. Returns a video generation job ID for polling. Video Status Polling Continuously checks video generation status via OpenAI API. If status is "completed": proceeds to download. If status is still processing: waits 1 minute and retries (polling loop). Video Download & Storage Downloads the completed video file from OpenAI. Uploads the MP4 file to Google Drive (root folder). Generates a shareable Google Drive link. Logging to Google Sheets Records all generation details in a tracking spreadsheet: Product description Video URL (Google Drive link) Generation status Timestamp Summary Flow: Webhook Request → Generate Product Image (Gemini) → Extract Image Data → Generate Video (SORA 2) → Poll Status → If Complete: Download Video → Upload to Google Drive → Log to Google Sheets → Return Response If Not Complete: Wait 1 Minute → Poll Status Again Benefits: Fully automated video creation pipeline from text to finished product. Scalable solution for generating multiple product videos on demand. Combines cutting-edge AI models (Gemini + SORA 2) for high-quality output. Centralized storage in Google Drive with automatic logging in Google Sheets. Flexible webhook interface allows integration with any application or service. Retry mechanism ensures videos are captured even with longer processing times. --- Created by Daniel Shashko

Add Spending Analytics Extend the daily check-in to calculate: Weekly/monthly spending summaries Category-wise breakdowns Use additional Code nodes to process transaction history Important Notes ⚠️ Never trigger with normal messages - Only use app mentions (@botname) to avoid infinite loops where the bot replies to its own messages. 💡 Context Awareness - The bot remembers conversation history, so you can reference "yesterday", "last week", or previous transactions naturally. 🔒 Data Privacy - All your financial data stays in your Google Sheets and PostgreSQL database. The AI only processes transaction text temporarily. 📊 Backup Regularly - Export your Google Sheets periodically as backup. --- Pro Tips: Start with small test transactions to ensure everything works Use consistent person names for debt tracking The bot understands various formats: "₹500 cash food" = "paid 500 rupees in cash for food" You can batch transactions in one message: "₹100 travel, ₹200 food, ₹50 snacks"
